“Unfortunately, many default settings on data mining and statistical software automatically create decision trees or rules sets that are preprogrammed to distribute the cases evenly. This can be a huge problem when dealing with infrequent events or otherwise unequal distributions. Another way of stating this is that the program assumes that the prior probabilities or “priors” are 50:50, or some other evenly distributed ratio.” — Colleen McCue
Today’s WhatIs.com Word of the Day is decision tree, a graph that illustrates a decision-making process by listing every possible outcome as a branch of the tree. (Usually the tree appears to be growing sideways.)
Decision trees are useful for providing team members with a common view of possible outcomes for discussion purposes — but they can also (gasp) be used to assign values to possible outcomes and actually frame what a decision’s consequences would look like.
MBABullshit has a good video illustrating how a decision tree might be used when deciding whether to sell lemonade or candy.
“Stateless computing isn’t about having no state. It’s kind of a misnomer. It’s about where that state is stored.” — Jeffrey Birnbaum
Today’s WhatIs.com Word of the Day is stateless app. A stateless app is an application that does not record data generated in one session – such as information about user settings and events that occurred — for use in the next session with that user.
“The market for a mobility architecture might not be as large as one for a hot, new smartphone, but at least it’s a new direction that might work. It’s just a question of whether RIM wants to let go of device that it has so much invested in.” — Shamus McGillicuddy
“The orchestration software that drives the service catalog understands the processes required for each service listed in the catalog, as well what resources are available in the private cloud architecture to support it. When the user selects a service from the catalog, the orchestration system takes over, launching a series of automated tasks to allocate the server, storage and networking resources for the service.” — Michael Brandenburg
Today’s WhatIs.com Word of the Day is cloud orchestrator, industry lingo for software that manages the interconnections and interactions among cloud-based and on-premises business units.
“Some observers feel Microsoft is working toward making Exchange Server backups completely unnecessary. The idea is that Database Availability Groups will eventually make Exchange resilient enough that you won’t need backups.” — Brian Posey
“There’s a lot to like about the idea of app wrapping. First of all, ensuring that encryption and authentication is present at the app level means that device level security is not nearly as important. So BYOD, managed or unmanaged devices—that all doesn’t matter. And with app wrapping, you can add security features to pre-existing apps.” — Jack Madden
Today’s WhatIs.com Word of the Day is app wrapping. App wrapping is a big deal in mobile application management (MAM) because it allows an administrator wrap a security policy around a third-party mobile app.
“The new growth area for chips now is the smartphone market. Apart from people who play video games, the demand for better and faster computers has waned. In the smartphone market, however, that demand is massive.” — Daniel Emery
Today’s WhatIs.com Word of the Day is Ivy Bridge, the code name for Intel’s third generation of quad core processors. The Ivy Bridge processors employ 22-nm (nanometer) architecture, a drop of almost 1/3 relative to previous chips.
David Emery explains why there’s so much buzz about Ivy Bridge
“My view is that crowdfunding will be really important in some industries, but not in all. A good example is technology companies. If you are in an early stage, tech startup, especially in Silicon Valley, and you can’t raise money from Angels or VC firms, that is a very bad sign.” — Ryan Caldbeck
Today’s WhatIs.com Word of the Day is crowdfunding, which is financing a startup project with relatively modest contributions from a large group of individuals, rather than seeking substantial sums from a small number of investors. It’s been a big buzzword since President Obama signed the Jumpstart Our Business Startup Act.
“Not only can your photos be shared through Lytro’s site, once your images are uploaded to Lytro’s servers, you can share them all over the web (via email, Facebook, etc.) with the use of a Lytro embedded player, much like the one used to share YouTube videos. That way, anyone looking at your photos in the player won’t need any sort of extra software, they can just click anywhere on the image to shift focus.” — Grant Hatchimonji
Today’s WhatIs.com Word of the Day is light field photography, an imaging technology developed (pardon the pun) by Lytro that makes it possible to adjust the focus in an existing picture. The cool thing is that you probably won’t have to buy a $500 light field camera to fool around with this photo tech — you’ll be able to mess around with it right from your iPhone or Android phone once they figure out how to the heavy lifting (processing) in the cloud.
Overheard in the tech blogosphere is like an impressionist painting about information technology. Close up, it’s just a bunch of colorful quotes. Take a step back and look at all the posts together — and you begin to see a picture.
